Do you waste a lot of time online? Time that could be better spent doing something productive? Seeing as you’re currently reading this blog, I’d wager that the answer is yes. Well, worry no more, because Steve Lambert of Eyebeam Lab’s recently released an app for OSX that could help boost your productivity.

The app is called “Self Control”, and you can configure it to prevent you from partaking in a number of online time-wasters such as checking Twitter, or checking on your fantasy basketball stats.

From the app description:

Is email a distraction? SelfControl is an OS X application which blocks access to incoming and/or outgoing mail servers and websites for a predetermined period of time. For example, you could block access to your email, facebook, and twitter for 90 minutes, but still have access to the rest of the web. Once started, it can not be undone by the application or by restarting the computer – you must wait for the timer to run out.

Wow, that sounds pretty intense, but we like the idea.

If you haven’t yet clicked off to check your email yet, you can check out and download the app over here. Sorry Tiger users, but this baby is Leopard only.
